REPAIR-TOOL.

Specification of Letters Patent.

Application filed December 23, 1912. Serial No. 738,307.

Patented Sept.'23,'l913.

an improved tool for repairing rubber tires.

A further object of our invention is to provide a strong and durable tool for-toroily expanding punctures or openings in tires and adapted to be positively locked in expanded position to permit the convenient insertion of repair material.

In the accompanying drawings forming a part of this application in which similar reference symbols indicate corresponding parts in the several views :--Figure 1 is a perspective view, illustrating one embodiment of our invention, with the cooperating expanding members tightly clamped in closed position; Fig; 2 is a similar view,

showing the cooperating expanding members positively locked in open position; and

Fig. 3 is an enlarged detail view, showing our improved tool applied for expanding a tire puncture.

Referring to the drawings, a pair of bent levers are pivotally connected at their bent portions 1 to provide diverging jaws 2 and 3, and handle portions l and 5. A pair of cooperating expanding members (3 are shown extending perpendicularly from the jaws 2 and 3 and terminating in outward barbed portions 7; said members being provided with plain inner faces adapted to engage throughout their length in closed position. A confining link 8 is slidably mounted on the lovers in position to engage a series of recesses 9 in the outer edges of the diverging handle portions 4 and 5, for rigidly locking the cotiperating expanding members in their open position. The outer edges of the jaws 2 and 3 are provided with seats 10 for clampingly receiving said link 8 to lock the coope'ating expanding members 6 in their closed position; said seats being provided with inclined end portions 11 for wcdging said link thereon.

In the operation of our invention, the co operating members 6 are inserted in a tire puncture, and the handles t and 5 tightly gripped to force said members apart for expanding the puncture. The link 8 is then slid along the lovers into engagement with the recesses 9 in the divergin outer edges of said handles for firmly loc liing said expanding members 6 in open position against the pressure of the tire. In this position of the parts, the barbed ends 7 of the expanding members (3 extend beneath the inner surface of the tire and ell'eetively prevent the expanding pressure exerted on the tire from forcing, or crowding, the latter past the innor ends of the expanding members 6; there by permitting the ready insertion of repair material through the expanded puncture, and eliminating danger ol injury to the tire.

to have illustrated and described pre- 'lerred and satisfactory constructions, but

changes could be made. within the spirit and scope of our invention.

A. tool comprising a pair of bent levers pivot ally connected at their bent portions to provide diverging jaws and handles, cooperating expanding members extending perpendicular-1% from said jaws and terminating in bared portions, series of recessed seats formed in the outer walls of said diverging handles, a confining link slidably mounted on said levers for engaging such seats to lock said expanding members in open position, and seats formed on the outer walls of said diverging jaws for rcceivlng said link and provided with inclined portions for wedging said link thereon.

In testimony whereof we allix our signatures in presence of two witnesses. BENJAMIN V. MAXWELL. LUKE A. NIGKERSON. \Vitnesscs as to Benjamin V. Maxwell:
